ROOFING Filed Oct. 10. 1938 Patented Feb. 10, 1942 UNITED STATESPATENT'OFFICE 3 Claims.

My invention relates to roofing and includes among its objects andadvantages an improved fastening means for holding the edge of a roofingshingle or similar element down against a lifting force exerted by thewind or from any other cause. I

In the accompanying drawing:

Figure 1 is a fragmentary plan view of a section of a roof provided withfastening clips according to the invention;

Figure 2 is a fragmentary section on line 2-2 of Figure 1;

Figure 3 is a plan view of the parts illustrated in Figure 2; and

Figure 4 is a plan diagram indicating how the clips can be formedWithout waste out of a sheet of material.

In the embodiment of the invention selected for illustration, andreferring first to Figure 4, each clip comprises a first arm l and asecond arm I2 diverging at an acute angle in substantially the shape ofthe letter V. The remote edges of the arms [0 and I2 come together toform a point at M, and the adjacent edges come together to define acrotch at l6. Due to the acute angle between the arms, the distance fromthe point 14 to the crotch I6 is materially greater than the width ofeither arm, so that the junction of the two arms forms a body portion N3of somewhat greater extent and stiffness than any other portion of theclip. Substantially midway of its length the body portion is bent atright angles as clearly shown in Figure 2 to carry its point l4downwardly. A little to the rear of the crotch l6 both the arms are bentdown at right angles as clearly indicated at 24 in Figure 2 to extenddownwardly parallel to the downwardly projecting point l4. At a distancefrom the bends at 20, substantially equal to or very slightly less thanthe thickness of two of the roofing elements to be fastened by the clip,both arms are bent again at right angles as indicated at 22 in Figure 2to extend back in parallelism with the portion of the body adjacent thecrotch l6.

As made up at the factory, the angle at is preferably left a littlegreater than a right angle so that the clip may be assembled asindicated in Figure 2 with the end horizontal reaches of the arms In andI2 underlying the shingle edge 26 and the edge of the overlying shingletab 28 with the body portion l8 extending up sufficiently to have thepoint l4 clear the upper surface of the shingle tab 28 as indicated indotted lines in Figure 2. Then a simple pressure or blow will force thepoint [4 down into the full line position of Figure 2 and the assemblyis complete.

It will be noted from Figure 4 that, except for the small corner piecesat 30, a strip of material of indefinite length may be out up to form aplurality of clips in such a way that all the metal is used in the clipsand there is no waste.

I prefer to strike up a triangular pointed tooth at 32 in each leg,which will embed itself in the lower surface of the adjacent overlyingshingle and hold the clip with additional firmness against slipping outof place, both before and after the tang I4 is driven home.

Without further elaboration, the foregoing will so fully explain myinvention that others may, by applying knowledge current at the time ofapplication, readily adapt the same for use under various conditions ofservice. It will, for instance, be obvious that while I have illustratedin Figure l a roof made up of shingles 32, each of which has twosemi-hexagonal tabs 28 projecting from its lower edge, my clip isequally applicable to the fastening down of Dutch-lap shingles eitherwith or without individual horizontal adjustment for each shingle,individual hexagon, or the so-called French method shingles with theclip positioned at the lower corner of the shingle, or any other of manypresent or future types of overlapping roofing shingles.

I claim:

1. A roofing clip comprising a fastening tang; a top reach lying at anangle to said tang; a riser reach lying at an angle to said top reachand in general parallelism with said tang; and an anchor reach lyingsubstantially at an angle to said riser reach generally parallel to saidtop reach, said tang and all said reaches being bent up out of a singleV-shaped piece of sheet metal.

2. A roofing clip comprising a pointed fastening tang adapted to bedriven downwardly from above into a piece of roofing material; a topreach lying substantially at right angles to said tang and adapted tolie horizontal in contact with the upper surface of a piece of roofingmaterial receiving said tang; a riser reach shaped and arranged to lievertically against the aligned edges of two pieces of roofing material,the upper one of which receives said tang and underlies said top reach;and an anchor reach of greater length than any other reach, lyingsubstantially at right angles to said riser reach and shaped andarranged to extend under both of two pieces of roofing material fastenedtogether by said clip; the angle between said riser reach and said topreach being greater than a right angle before said tang is driven in,whereby said tang is held in position ready for driving; said anchorreach, riser reach, and the portion of said top reach adjacent the edgesof said pieces of roofing material being in duplicate and spaced apart,and diverging from each other in the direction away from said tang.

3. A roofing clip comprising diverging arms constituting a V-shapedpiece of sheet metal; 10

the arms of the clip having tapered ends; the interior edges of saidtapered ends being straight line prolongations of the interior sides ofthe arms themselves; the exterior edges of said ends being parallel toeach other and to the median axis of the device; whereby a plurality ofclips may be formed from a strip of material of uniform width withoutwaste along the edges of said strip.
